Not a Tesla owner but I would have thought that Musk & co would be able to state exactly when the Autopilot wasn't engaged and when it was just from the logs and yet they are 'unclear'. Is that another way of saying that the AP bailed and went "here human, fix this" in the final seconds? I mean, how hard can it be to check the logs from moment of impact backwards and state "it wasn't turned on for the journey" or "it was turned off 3 minutes before the crash". Unclear huh?
